SPECIFICATION forming part of Letters Fatent No. 419,553, dated January 14, 1890. Application filed Juno 6, 1889- Serial No. 313,355. (Model.)

To @ZZ whom it may con/cern:

Be it known that I, JOHN A. PORTER, of St. Louis, Missouri, have made a new and useful Improvement in Permutation-Locks. of Which the following is'a full, clear, and exact description. t

The improvement consists substantially as is hereinafter set 'forth and claimed, aided by the annexed drawings, making part of this specification, in Which- Figure l is a side elevation of the improved lock, a portion of the lowest band being broken away. Fig. 2 is a View showing a portion of the lock in section and the remainder in side elevation. Fig. 3 is a view in perspective showing a combined ring and banda portion thereof being broken awa);- Fig. 4, a view in perspective of Line "bodyI of the lock; Fig. 5, a cross-section on the line 5 6 of Fig. 2, the recesses in the rings being in coincidence with the bars of thelink; Fig. 6, asiinilar cross-section, the recesses in the rings not being in coincidence with the bars of the link. Fig. 7 is a view in perspective of the link. Fig. 8 is a View in perspective of one of the bands, and Fig. 9 is a View in perspective of one of the rings. l

` The same letters of reference denote the same parts.

The improved construction consists, mainly, of the body A, the link B, a series of rings O C O2 Os C4, and a series of bands D D D2'D3 D4. The body has a shoulder a at its lower end, and it is grooved longitudinally at aa. The grooves, as shown in Figs. 2 and 4, extend throughout the length of the body, and they may extend into the shoulder d, as shown, and

to drain the grooves perforations d2 may ex- Vtend through the shoulder. At its upper end the body has a threaded projection c3, onto which a cap a4 is screwt l, as shown, and as presently described. The linkBis a U-shaped part adapted to be connected with the remaining portion of the device by slipping' its bars b into the grooves a a', as shown in Figs. 2, 5, and 6. The inner portion b only of the bar cntersthe groove. The outer portion o2 of thebar is designed to coact with the rings C C', &c., to which end a series of notches b3 are formed in the portion b2. The rings at the periphery thereof are notched, the notches c extending vertically in the ring, substantially as shown, and, as a series around the ring, they also have an inwardly-projecting tiange c', and such iiange is notched at c2 c2. The rings O, &c., are fitted to be passed, one after the other, onto the body, as shown. The bands D, the., belong, respectively, to the rings C. dac., and they are fitted to be slipped vertically onto the rings, as shown in Fig. 3, and on the inner side thereof the bands, as shown in 8, have inwardly-extending projections d, which, when the band is applied to the ring, engage in the notches c, as shown in Figs. 3, 5, and 6. Upon the outer side thereof the bands bear a series of numerals or other characters d', said numerals or characters corresponding in number to the notches c and respectively opposite the notches c.

The parts of the lock are assembled and the lock operated as follows: The rings, bearing `their respective bands, are slipped successively onto the body A, and then secured in place thereon by means ot' the cap a4, as shown. The link B is then attached by slipping its bars b b into the openings formed partly outA ot' the grooves d c and partly out of the notches c2 c2 in the rings, and the link islocked in thatpositionby simpl y rotating one or more of the rings (and bands) suliciently to cause the notches c2 c2 to be out of line with the link-bars b b. The notches b3 in the link-bars permit the rings to be thus rotated, for as the ring is turned around its iiange c moves in that one of the notches b3 which is opposite said flange, and the main portion c3 Y of the ring moves around the round or full portion b2 of the link-bar. The link, newboing locked, cannot be unlocked and withdrawn from its position in the lock without iirst rotating the ,rings (and bands) back again in that position in which their notches c2 c2 are in line with the link-bars, whereupon the link can be withdrawn. It' more than one ring is misplaced-Lsay two or three rings, or even the entire series-then all those misplaced rings must be brought into line. It is the numerals d on the bands D Whichenable the operator to adj ust the rings as describedthat is, in applying the bands to the rings they are adjusted upon the rings according to a predetermined combination of numeralssay the combination O 5% 3 7, presented in Fig. l. That is, the upper band has its O-mark IJO opposite the notch c3 in the ring, the next lower hand has its sniark opposite the notch c2, the next lower hand has its B-mark opposite the notch c2, and so on. The operator, knowing; the combination, turns the rings around h vincans ot their respective hands and accordint,T to said combination, and the link is thereh)7 released. To change the conihination, the rings .and hands are removed from the lock-body and the hands changed upon their respective rings to suit the new combination desired.

I claiml. In a periirritation-padlock, the combination of the rings having,` the vertical equidistant grooves in their outer surfaces and provided with the inwardiy-standing flanges c', havingr the opposite seinicircular notches c2, and the correspondinghands having; equallydislant. numbers or marks on their outer snr laccs and the projections d on their inner snrl'aces, which proj eci/ions may he fitted into various grooves ff, l'or the purpose ol' bringinfcv various numbers or marks opposite Athe notches ffl, substantially as specified,

2. In a permutation-pmlloek, the combination, with thehodyhaving the vertical grooves a', and the link havingl the transverse notches L", ofthe rings having the outer vertical grooves c and the [langes c', provided with the opposite notches c2, and thehands having' n timbers or marks on their out-er surfaces and the projectlins u, on them innersurfaces, suhstantially as specilied.

3. The hcrein-described permutatiompadlock, composed of the body A, having` the grooves a', shoulder a, and threaded stein a3, the cap screwing on said stem, the link having the notches if, the rings having,` the `grooves c and flanges c', provided with the opposite notches el, and the bands numbered on their outer surfaces and provided on their inner surfaces with the projections d, substantially as speeiied.
